SPECIFICATION forming part of Letters Patent No. 649,984, dated May 22, 1900.

Application filed'De'cember 23, 1899. Serial No. 741,359. (Nonodel.)

To all whom, it may concern:

Be it known that we, LYDIA A. GOODSON, of Elgin, county of Kane, and CHARLES S. BUR- TON, of Oak Park, county of Cook, State of Illinois, citizens of the United States, have invented new and useful Improvements in Invalid-Beds, which are fully set forth in the following specification, reference being had to the accompanying drawings,forming a part thereof.

In the drawings, Figure l is a plan of a woven-wire bed-spring having the features which distinguish our invention. Fig. 2 is a vertical section at the line 2 2 on ZFig l through the bed-spring and mattress thereon, showing the parts in position of use. Fig. 3 is a similar view showing the parts in position occupied while removing or inserting the mattress-plug. Fig. 4 is a detail section of a displaceable device for supporting the mattressplug.

The purpose of this invention is to aord conveniences in caring for bedridden persons, and particularly to provide a woven-wire bedspring having the special appliances permitting the use therewith of a mattressprovided with an aperture closed by a removable section and having for that purpose a correspondin g aperture with displaceable supports for the removable mattress-section.

A A are the end sills of the frame of the woven-wire spring.

B BB, &c.,are the longitudinal coils,which are interlaced to form the spring and of which a certain number at the middle part of the width of the spring are interrupted or cut OE to form the aperture in the spring.

C Care rods or bars to which the severed ends of the coils B B are connected, said rods or bars extending across the ends of the aperture X. The ends of the coils B are secured to these rods or bars by having the wire formed into an eye b', which encircles the rods, of which the preferable form is a cylindrical rod or wire, as shown. The corresponding ends of the two rods C C areconnected `by coiled springs D D, which are calculated and designed to be heavy enough to offer a resistance to stretching equal to that which would be offered by all the coils of the bed-spring, which are cut out to form the aperture X, so that when the severed ends of the interrupted coils B are connected to the cross-bars C C and said cross-bars are connected by the Springs D D the longitudinal extensibility and `elastic reaction of the middle portion of the bed-spring, in which the aperture constitutes an interruption, are substantially the same as they would have been if the aperture were not formed and all the coils were continuous from `end to end, so that the spring as a whole has substantially uniform stiness throughout or as nearly uniform with the aperture as it would have been without the aperture. The aperture X is preferably made large enough to permit the removable piece E' of the mattress E, which is formed to fill a corresponding aperture in the mattress at a position directly over the aperture in the bed-spring, to readily pass through said aperture X, which is therefore a little greater in each dimension than the aperture in the mattress, and in order to support the plug or removable piece E of the mattress We provide rods F F, parallel to and suspended from the rods C C, respectively, and we lodge on these suspended rods F the rods or bars G G G, Whose opposite ends are introverted or hooked, so that when both ends are lodged upon and engaged with the rods F F they are not liable to be accidentally disengaged, and we make these rods G G long enough between the bends of the hooks to allow the springs D D to stretch to the maximum extent to which they are liable in the use of the bed without experiencing any restraint by reason of the connection which the rods G G form across the length of the aperture X. This accommodation may be afforded merely by the swing of the suspended rods FF if they are suspended loosely, so as to swing; but if they are formed, as they may be, rigid with the rods C C (and they may be formed integrally with such rods, respectively) the necessary accommodation should be provided in the length of the rods G, and the hooks at the ends of these rods should in that Cas@ ha Suhioutly @Xteuulod @that theV rods' willl not become disengaged when theV springs D "Dare 'most contracted 'and the" aperture X is shortest. In order to facilitate the displacing of the rods G to remove or admit the mattress-plug E and the restoration We connect th'ethroio rods 'by '1.isbirrohainis-.or-v other iiexible connection H H, said chains extending at one end to one of the springsD and being attached thereto, the length of chain to the spring and length of chain h tween the rods-successively being such as to cause the rodswh'en tlechains-"drawn taut to be properly distributed-and; located over the width of the aperture' X. l To the rod.
